Snapper farming in tropical regions is expanding, with welfare challenges around adaptation to captivity and crowding stress particularly significant.
Snapper welfare in captivity is complicated by their territorial and predatory nature. High stocking densities trigger chronic aggression, causing fin damage and stress. Snapper also show pronounced startle responses to sudden disturbance, making net handling particularly stressful. Reduced stocking density, structured environments that reduce line-of-sight aggression, and improved handling protocols including minimising air exposure substantially improve welfare outcomes.
